What are the rules of a quadrilateral?
Rules for Quadrilaterals. 1. These rules are the same for all quadrilaterals: a) They are all polygons. b) The interior angles ALWAYS add to 360 degrees. 2. These are the rules for rectangles a) The diagonals of a rectangle are congruent and bisect each other. b) Opposite sides are ALWAYS parallel.
What is the formula for a quadrilateral?
The formula for an irregular quadrilateral — which is a polygon that has four sides that are of unequal length — is the same as that of a trapezoid. The formula is a + b + c+ d = perimeter. For example, suppose that a quadrilateral has sides with lengths of 1, 5, 3 and 4 inches.
